JSOFA
Observed Position.
"Observed" Az,ZD means the position that would be seen by a
perfect geodetically aligned theodolite. (Zenith distance is
used rather than altitude in order to reflect the fact that no
allowance is made for depression of the horizon.) This is
related to the observed HA,Dec via the standard rotation, using
the geodetic latitude (corrected for polar motion), while the
observed HA and RA are related simply through the Earth rotation
angle and the site longitude. "Observed" RA,Dec or HA,Dec thus
means the position that would be seen by a perfect equatorial
with its polar axis aligned to the Earth's axis of rotation..
